The East Side Access (ESA) project provides new Long Island Rail Road services to the east side of Manhattan, supplementing the existing service to Penn Station on Manhattan's west side and Atlantic Terminal in Brooklyn. ESA will serve approximately 162,000 customers a day, providing a faster and easier commute to the east side of Manhattan in a new 8-track terminal and concourse below Grand Central Terminal. The project encompasses more than 13 km of tunnelling.
